The ocean plastic tile does not measure plastic in real time with sensors or satellite data. It applies a published annual estimate — 11 million metric tons entering the oceans each year — and spreads that total evenly across the calendar year.
How the counter works
- Start with 11,000,000 metric tons per year.
- Measure how much of the current calendar year has elapsed.
- Display that fraction of the annual total, updating continuously.
On 1 July you would see roughly half of 11 million tons — not because we have verified exactly that much has entered the ocean since January, but because the model assumes a steady flow through the year.
This is the same year-to-date method used for every live stat on Trashed.Earth.
Where 11 million tons comes from
The figure comes from Breaking the Plastic Wave, a landmark analysis by Pew Charitable Trusts and SYSTEMIQ. Their modelling found that without major policy and industry changes, roughly 11 million metric tons of plastic enter aquatic ecosystems every year — rivers, lakes, and oceans combined.
That flow is not all visible as floating bottles. Much of it arrives as microplastic fragments, lost fishing gear, and debris carried from land through rivers. The report also showed that current commitments would barely reduce the trajectory; plastic production keeps rising.
We use 11 million tons as a round, widely cited anchor that reflects the scale Pew and SYSTEMIQ documented — not because every gram is directly measured at sea.
What this number does not capture
- Plastic already in the ocean — the counter tracks new inflow, not the estimated 100+ million tons already there.
- Exact timing — storms, monsoon seasons, and cleanup efforts make real flows uneven; our counter smooths them out.
- All plastic pollution — this stat focuses on material entering aquatic systems, not total plastic waste generated on land.
Why we show it anyway
Most plastic reaching the ocean comes from mismanaged waste on land. A counter cannot show every river mouth or landfill leak, but it can make the continuous nature of the problem tangible. Read this as a modelled annual inflow, not a live tally verified shipment by shipment.
